Now, when in battle against a Trainer, Whirlwind will force a switch with a randomly chosen Pokémon from the Trainer's party. If there isn't another Pokémon, Whirlwind will fail. It also has a priority of -1. If two Pokémon use Whirlwind at the same time, the faster one will fail and the slower one will phaze it out. Otherwise, it is the same as in Generation I.

Whirlwind will fail when used against Pokémon with the Ability {{a|Suction Cups}} or rooted by {{m|Ingrain}}. In a Trainer battle, rather than switching out to a random Pokémon in the party, it switches out to the next Pokémon in line that has not fainted. In Generation III Whirlwind has a priority of -5, which was decreased to -6 in Generation IV. If two Pokémon use Whirlwind at the same time, instead of the faster one failing, the faster one will go first and phaze the slower one out.
